Megan Racing Down-pipes for the BMW 1 and 3 series (equipped with N54B30 twin
turbo motor) are made of durable 100% T-304 Stainless Steel piping that
is polished to a mirror-like finish. This Down-pipe replaces the OEM
exhaust piping with all of its restrictive bends while increasing the
inner diameter of pipe; this greatly increases exhaust flow and reduces
turbulence within the system, as a result freeing up high-end horsepower
and mid-range torque. Essentially the missing link to your exhaust
system; this down-pipe will give you competitive edge that you have been
looking for. Expect an increase in exhaust tone due to freed up exhaust
flow. (NOTE: The down-pipe is for off-road use only and is not intended
for public highway use.)
